With my test image, $imageinfo contains 3 keys after call, but return value is false. There is no notice, warning or other information. Calling same function without $imageinfo returns correct result. tested PHP-Versions: - 5.5.9 - 7.0.2 Test script: --------------- $info = array(); $sizeInfo = getimagesize($fileName, $info); // returns false, $info not empty $sizeInfo = getimagesize($fileName); // returns correct size information Expected result: ---------------- Better solution should be: - return correct size information like call without $imageinfo - trigger an error or warning, if collecting data for $imageinfo causes an error ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=71848&edit=1
